Re: 87 YJ 4.2 -> 4.0 swap questions
thanks earl - a few questions then:
can i take the fuel pump out of the cherokee and install it into the YJ? and what if i was to swap out my entire engine/TC/trans with the one from the cherokee? wouldnt that eliminate the need for installing a CPS and the adapter plate? i suppose i'd need a different driveshaft... and perhaps front drive shaft? and the springs? thanks for your help... bennett |

Re: 87 YJ 4.2 -> 4.0 swap questions
The fuel tanks are different, so you can't put the pump from the Cherokee in
the Wrangler tank. Now I don't know whether the Cherokee tank fits in the Wrangler, but I do know that you need an FI tank to make the 4.0 work. An external aftermarket pump will "work", but as I pointed out they are problematical. Before thinking about swapping the entire drive train, you'd better get out a tape measure and see what is what. The Wrangler drive shaft is too short as it is, as people find out when they install lift kits. If the Cherokee engine mount to TC tail shaft distance is longer, then it won't fit. If it's a Selectrac, it "really" won't fit. I haven't made this measurement myself, but I am pretty sure that you will find out, that the Cherokee drive train is too long. Wrangler springs from www.4wd.com are not too expensive. The stock springs on a Wrangler are pretty flat, so your existing springs may not be as bad as you think. The best way to get the old bushings out is with a gas wrench.

Re: 87 YJ 4.2 -> 4.0 swap questions
thanks all.
Earl - can i ask you to clarify some things? 1st off - i am clueless as to the nature of the 'Selectrac' and 'Quadratrac' so what l do i need to look for to detemine their presence? 2nd - besides the driveshaft length - which is pretty obviously different i would imagine - can't i just swap my tired old Peugeut 5sp with the AT that comes with the Cherokee? since this is the tranny and TC that comes with the motor, it would thus eliminate any need for adapters for the CPS, as well as the problem of pilot bushing mismatch, and for finding a 4.0/5sp manual computer... isnt that right? all i would need would be a YJ driveshaft with the correct spline count yes? i assume my stock (5sp) shaft wont fit - correct? sorry for all the questions, trying to figure out if this is a good idea... cheers, bennett |
